Product Overview

NB-IoT non-magnetic sensor valve-controlled remote transmission water meter is a water measurement instrument based on a wet multi-stream water meter, which adopts non-magnetic sensor electromechanical conversion technology and uses NB-IoT network communication for data remote transmission. It is suitable for Water metering for residential households.

Product features

• Using NB-1OT narrowband IoT wireless communication technology;
• Wide coverage and more convenient communication;
• Remote meter reading, with valve control function, easier to manage water meters;
• Data is automatically saved without fear of base station failure or server downtime (data saving time limit is optional);
• Support online real-time upgrade;
• Ultra-low power consumption design, long service life;
• The non-magnetic sampling technology is not afraid of magnetic attacks, and it also has forward and reverse metering functions.

Traffic parameters

Model diameter	Length*width*height mm	Overload flow Q4 m3/h	Common traffic Q3 m3/h	Boundary flow Q2 m3/h	Minimum flow Q1m3/h
DN15	165*99*136	3.125	2.5	0.04	0.025
DN20	195*99*136	5	4	0.064	0.04
DN25	225*99*106	7.875	6.3	0.1	0.063

Maximum allowable error A. The maximum allowable error in the low zone from including the minimum flow rate (Q1) to excluding the boundary flow rate (Q2) is ±5%; B. The maximum allowable error in the high zone from including the boundary flow (Q2) to including the overload flow (Q4) is ±2%. (±2% when water temperature ≤30°, ±3% when water temperature >30°)
